MODIS/Aqua Snow Cover Monthly L3 Global 0.05Deg CMG, Version 6

This data set reports monthly average snow cover in 0.05 degree (approx. 5 km) resolution Climate Modeling Grid (CMG) cells. Monthly averages are computed from daily snow cover observations in the MODIS/Aqua Snow Cover Daily L3 Global 0.05Deg CMG (MYD10C1) data set.

Version Summary:

Changes for Version 6 include:

  • Fractional Snow Cover (FSC) previously used as input to this data set has been replaced by Normalized Difference Snow Index (NDSI) snow cover;
  • Aqua MODIS band 6 data have been restored to scientific quality using a Quantitative Image Restoration (QIR) technique. Aqua now uses the same snow detection algorithm as Terra.

Geographic Coverage

In August, NSIDC removed all MODIS Version 6 browse images due to errors. The science granules were unaffected. We have begun replacing the deleted images with corrected versions, starting with forward processing from 10 November 2016 onward. Historic browse images will be replaced from the beginning of each mission and moving forward. In the meantime, browse data are available for MOD10_L2/MYD10_L2 and MOD29/MYD29 through NASA's Earthdata Search.
